Specification of Letters Patent. Patented Feb. 26, 1918.

Application led November 4, 1915. Seal No. 59,510.

To all whom it may concern.'

Be yit known that I, MINOR E. CHAMBER- LAIN, a citizen of the United States residing at Lebanom' county of' Laclede, and State oi' Missouri, have invented a new and useful Resilient lVheel, of which the following is a specification.'

This invention relates to resilient wheels and more particularly to wheels for vehicles having an inflatable tire and consists in the novel Construction hereinafter more fully disclosed.

An object of the invention is to provide in resilient wheels an inflatable tire rovided with a metallic shield mounted within the outer casing which will prevent the penetration of the tire and the consequent puncture thereof and which, at the same time, will not reduce to any appreciable extent the resiliency of the wheel.. v

Another object of the invention is to provide in tires having resilient wheels a ilexible and yieldable shield comprising a series 'of movable plates joined together to form the annular shield adapted to be mounted within the outer casing of the tire.

With these and other objects and advantages, attainable from the construction hereinafter disclosed, in view I have produced the new article of manufacture 'comprising the parts of novel design arranged and combined in the novel manner hereinafter de-y scribed and claimed, reference being made in the course of the description to the accompanying drawings, in which I have illusY trated specilic embodiments of the invention, and in whichp Figure 1 is a'vertical section through a portion of a wheel. illustrating an embodiment of the invention, .taken substantially on the line 1 1 of Fig. 2.

Fig. 2 is a cross section through the vsame parts of the wheel construct..fn, thecross section being on a line such as 2-2 of 1.

Fig. 3 is a broken plan view of a section of a shield designed in accordance with the invention and illustrating one embodiment thereof.

pressed blank-from which one section ofthe4 Fig. 8 is a view of the same parts illustrated in Fig. 7 and taken on a cross sectional line, such as 8-8 of Fig. 7.

Fig. 9 is a section of the guard or shield designed lin accordance with the specific embodiment of the invention illustrated in the two preceding figures.

Fig. 10 is an edge view of the section of the shield illustrated in Fig. 9.

Fig. 11 is a broken compressed plan view of a blank from which the shield illustrated in the next'preceding g'ures is made.

The wheel includes the 'usual spokes 1 which support at their outer ends a rim member 2 upon which is mounted an outer casing' of an inflatable tire.- It will be understood that the method 0f attachment of the outer casing to the rim member may be of any of the known designs, that illustrated type in which beads 4 are receivedin chan-l nels 5 of the rim member 2. Within the casing 3 is inclosed the inflated inner tube 6.

The impenetrable shield or guard for preventing the puncture of 'the inner tube 6 comprises relatively movable sections joined together so that after the inner tube has been iniiated the shield will be held in position below the tread of the outer casin and will conform in its movement substantially to the movement of the casing. Thus, while shielding the inner tube from penetration it will at the same time so 'conform to the movement of the resilient tire as not to diminish to any the tire.

Invention is broadly inthe provision of the shield or-guard consisting o'f relatively.

movable sections and made of several satis- 'in the' drawings being ofthe clencher appreciable extent-the resiliency of factory designs, some of which Ihave illustrated in the drawings and, in order that the specific. constructions may be understobd, I wil-l describe them as illustrated.

The design of shield illustrated in- Figs. 1 to 6 inclusive csmprises a. series of metallic Iplates 7 formed from a, blank speciftally illustrated in Fig. 6. By reference to-Fig. 6

it will be observedl that the plate, wh1ch 4 form to thecontour of the outer casin constitutes one of the movable sections of the shield, is with extending lips 8 and with lips 9 spaced therefrom. 'The lips 8` and 9 are adapted to be upturned over the edges of the adjacent plate, the plates `being held together by the over-turned lips. Adjacent to' the end 0pposite to the end in which the lips 8 are provided, 'are lips 10 adapted'to be foldedove'r, as. own specifically in Figs.- 3' and 4 soV that 'when the plates are' assembled the abutments lformed from the lips 10 will bedisposed between the inner adjacent edges of thev turned-.over lip's 8 and 9. The sections of the shield will be free to move the dis; tance between the adjacent edges of lthe respective li 8. and 9.

The sur ace ofthe shield is curved to crn- 3v elow the tread thereof, and is adapte to be held in place between the inner tube and the outer casing, the pressure 'in the inner v per.' edge tube vforcing' Vthe shield against the inner wallof'the outer tube. A protecting guard 11 of canvas isV interposed `between the upoftheshield Aand the inner wall ofthe outer casing and a similar guard 12 of canvas. or other suitable material is intergposed bet-weenftheouter Wall of the inner .casing and. the inner wall ofthe shield., The'guardsll and 1 2 prevent damage to the surfaces, it being un-4 derstood' that theyh are heldfirmly in place by the pressure fromwithin the tire.

The of the shieldillustrated in Figsgf( toll inclusive comprises-sections made from afblank i3 in the form specilically` illustrated in Fig. 11, which blank it will be observed includes adjacent to one end outwardly extending portions 14 having-lips 15 at their outeredges. .The portions 14 are adapted to be folded backwardly upon theedges of the-blank 13and the ex- ...tremity of the matching section disposed betweenthe :Eaceof-the blank 13 andthe.

blank. I n thisv construction the relative elba inner surfaces of said backwardl folded ortons 14', and the lips 15' being. epressed ownwardly and extendin into aslot A16 formedv at the opposite en 'of the adjacent movement of the sections is limited by the'v abutments, formed .from the depressed "lips l '15 engaging the, ends of theslot 16.

each of the formsofthe invention illusthesame basic prinviates the deficiency of a rigid metal shield and preserves the re'siliencyof the Wheel.

I amxaware that the same principle may 4in additional forms,
